1 Claim.

This invention relates to an adjustable ventilator shield for windows,and one of its objects is to provide a ventilator shield with a pair ofguides in which the shield may be slidably adjusted, and to providepivotally adjustable supports for the guides, so that the shield may bepositioned in different planes of body adjustment, either inclined orvertical, and in spaced relation to the window sash.

Another object of the invention is to provide brackets for pivotallyconnecting the ventilator to the sides of a window frame, of simpleconstruction, and which will safely hold the ventilator shield ordeflector in any position of adjustment, within the range of effectiveadjustment.

With the above and other objects in view the invention comprises certainnew and useful constructions, combinations and arrangements of parts,clearly described in the following specification, and fully illustratedin the drawings, in which:

Fig. 1 is a perspective view showing the device supported in a verticalposition, with the sash partly raised.

Fig. 2 is a vertical sectional view, taken on line 2-2 of Fig. 1,looking in the direction of the arrows.

Fig. 3 is a similar view, showing the ventilator disposed in an inclinedposition.

Fig. 4 is a detail vertical sectional view, taken on line tl of Fig. 2,looking in the direction of the arrows, showing a slightly widerdeflector or shield.

Referring to the drawings, which illustrate the invention, 5 designatesone side of a conventional window frame and 6 the companion side. On theside 5 a circular bracket plate I is secured by the screws 8 and 9, andto this bracket plate the bracket arm I0 is pivoted by the pin H. To theframe side 6 the bracket arm [2 is pivotally secured by a bracket plate,similar to the plate I, but not shown.

On the outer end of the bracket arm I0 a channel guide I3 is pivotallysecured by the pin l4. On the outer end of the bracket arm l2 thechannel guide '15 is pivotally secured by the pin [6. The two bracketarms I0 and 12 are supported by their base plates in a common horizontalplane, and are of equal length.

The channel guides are arranged in opposition to each other and also areof equal length, with the grooves Ind and 12b confronting each other. Inthe groove [2?) the end of the plastic or glass shield pane or plate I!is disposed, and in the groove [0a, the end of the plastic or glass paneor plate I8 is disposed.

The inner end portions of the panes or plates 2 I1 and [B are arrangedin overlapping relation to each other, and U-shaped guide hooks l9 and20 are provided for holding these overlapping portions against eachother for sliding adjustment.

Due to the fact that the channel guides l0 and 12 are entirelyindependent of each other, and the panes or plates l1 and I8 can beextended or contracted on each other, the unit can be adapted to fitnarrow or very wide windows.

Due to the tilting supports for the panes or plates I! and I 8, thedeflector or extensionable shield, may be supported in a verticalposition, as shown in Figs. 1 and 2, or in an inclined position as shownin Fig. 3.

Each of the pivotal connections is designed to offer a certain amount offriction, so that the adjustments made will not be accidentally changed.

It is understood that various changes in the details of construction,their combination and arrangement, may be made, within the scope of theinvention, as defined by the claim hereof.

Having described the invention, I claim as new:

An adjustable window ventilator, comprising a bracket plate secured toeach side of the window frame, a single bracket arm pivotally secured atone end to each of said bracket plates said bracket arm turning freelyfor about relative to the window frame, a pair of grooved guidespivotally secured to the other end of said. bracket arm intermediate theends of said guide, a deflector member, the side ends of said deflectormember being secured in the groove of each guide, said bracket armpermitting of turning of the guides with the deflector member for 360relative to said bracket arm, thereby bringing about the possibility ofpositioning of the deflector member at any predetermined angle over arange of at least of 180.
